TO ALL WHOM IT MAY CONCERN:

Be it known that I, THOMAS TRACY, of New Britain, county ofHartford,'and State of'Connecticut, have invented certain new and usefulimprovementsv in Machinery for Driving Wires into the Joints of' Butts;and I do hereby declare that the same is described and representedin thefollowing specification and drawings. And to enable others skilled inthe art to make and use 'thesa-me, I will proceed to describe itscon/structiony and operation, by referring to the dra\vings,lin whichthe same'letters indicate like parts in each of the figures.

This improvement relates only to that part of a butt machine whichperforms the work of holding, distribnting, and driving'thc wire intothe joints of'butts, without reference to any particular mode' ormechanism for applying the power for operating its partsgthenature .ofwhich consists in so constructing the' mechanism for' holding anddriving the joint wire into the joint of avbutt as to eifectuallyprevent it' or the driver from kinking. In the accompanying drawings-Figure l` is a top View. V l

Figure 2-is an end view of thcvdevice, which lies parallel with theendof a'butt, in readiness to receive the joint wire Figure 3 shows a topand end view ofthe driver-bar. I

a isa butt, placed'or moving through a` machine in the usual way, andresting at the point for receiving its centre pin or wire whichcompletes4 the joint of thel butt. d is the device or bed which 4liesparallel with the line of the end of the butt a, in and near the centreof which is arranged a sliding driver-bar, c, so as to move in astraight line with the centre lofthe butt, on the upper edge and nearthecentre of which is formed a driver, d, of about three equal sides,l andequal to the diameter of the wire of-thebutt. This bar or driver d isoperated in the yusua'l way of operating the'punch or driver usuallyemployed for driving the wire into lthe joint of butts. n one side ofthis driver-bar c, and at the forward end, is made a wedge formation, e,and a button,f, of aboutthe same thickness of the driver-bar c,below theedge of the driver: d, having its edge g curved for the wedge formationof the-driver-bar c to work against, so that as the driver moves forwardthe button recedes, and as .the driver moves back the button is' reactedby a spring, h. The object of this but-ton f is to form a bcd forthewires te rest upon. is a Slide-or cut-olf, arranged so as to moveback andforth in the bed, closely over the top edge of the driver d, andhaving its cut-oifvedge bevelled, so that its edge will slide betweenthe wires and separate one from the others, to b'e driven forward intothe butt-joint. c are wires placed in a receiver, the lower end of whichis, open directly at the end of the cut-off, so that the cut-otl`regulates their movements, and only one be discharged from the receiver at atime.

Now it will be seen that when the machineis set -in motion the wirescwill fall down between the sides of the bed-plate upon the button, thecut-oii moves forward over the upper side of one Wire. Thus it (thewire) is closely encased on four sides, when the driver-bar c d movesforward, forcing th-evwire'in a straight lin-e into' the joint of thebutt without the least liabilityof crpoking 0r kinking. v

I believe Ilhave thus shown the nature, construction, and operation soas to enable-a person skilled to make anduse the same therefrom.

What I claim, therefore,. and desire to secure byfLetters Patent, isv IClaim the spring buttonf, and tongued bar c, or their equivalents, incombination with suitable mechanism for operating said har,substantially iny the manner and forithe purpose as described.
